I am using MVC3 and getting country table from database and storing in cache. First time it get the data from caching but when I refresh the page its give me only datatable schema only. It give me only fields countryid,countryname, countrycode. But it dont give me data.
DataTable dt_Country = (DataTable)HttpContext.Current.Cache["Countries"];
if (dt_Country == null)
{
DataTable dt_State1 = new DataTable();
SqlConnection con = new SqlConnection(Common.ConnectionString);
con.Open();
SqlCommand cmd = new SqlCommand("ConstantsCountriesSelectAll", con);
SqlDataAdapter ada = new SqlDataAdapter(cmd);
ada.Fill(dt_State1);
HttpContext.Current.Cache["Countries"] = dt_State1;
dt_Country = (DataTable)HttpContext.Current.Cache["Countries"];
}
//dt_Country = (DataTable)HttpContext.Current.Cache["Countries"];
return dt_Country;

my linq method system from EF6 is returning $ref when I monitor results in fiddler. If I watch the local window in my webapi everything is populated correctly, but not in the actual results that are returned. It only affects the nested entries. anyone know what I am doing wrong? (I created models from database in EF6)
var student = dbEF.Accounts
.Where(x => x.AccountNumber == acctNum)
.Select(x => new DTOCrmDetails()
{
AccountNumber = x.AccountNumber,
CommissionId = x.CommissionId,
Commission = x.Commission,
ManagerID = x.ManagerID,
ManagerName = x.Manager.ManagerName,
Manager = x.Manager,
Employees = x.Manager.Employees,
WireInstructionsUSD = x.Manager.WireInstructionsUSDs
//Mapping_ManagersExecutingBrokers = x.Manager.Mapping_ManagersExecutingBrokers
}).FirstOrDefault();
return student;
these are my settings.

You need to disable your lazy loading in the entity framework dbcontext.
something like this way:
dbEF.Configuration.LazyLoadingEnabled = false;
I have created connection via API through below code(Dynamics Crm: creating Connection entities via API
Entity connection = new Entity("connection");
connection["record1id"] = new EntityReference("contact", someContactId);
connection["record1objecttypecode"] = new OptionSetValue(2);
connection["record1roleid"] = new EntityReference("connectionrole", someConnectionRoleId);
connection["record2id"] = new EntityReference("incident", someCaseId);
connection["record2objecttypecode"] = new OptionSetValue(122);
connection["record2roleid"] = new EntityReference("connectionrole", someOtherConnectionRoleId);
var newId = service.Create(connection);
Question: I need to update connection role between two records.
If I understand the question correctly, you just need to proceed along the same road, using the Id you get from the Create to reference the record:
// Your code
Entity connection = new Entity("connection");
connection["record1id"] = new EntityReference("contact", someContactId);
connection["record1objecttypecode"] = new OptionSetValue(2);
connection["record1roleid"] = new EntityReference("connectionrole", someConnectionRoleId);
connection["record2id"] = new EntityReference("incident", someCaseId);
connection["record2objecttypecode"] = new OptionSetValue(122);
connection["record2roleid"] = new EntityReference("connectionrole", someOtherConnectionRoleId);
var newId = service.Create(connection);
// And then ...
connection = new Entity("connection"); // start from scratch
connection["connectionid"] = newId; // needed for the CRM to know what to update
connection["record1roleid"] = new EntityReference("connectionrole", yetAnotherConnectionRoleId);
connection["record2roleid"] = new EntityReference("connectionrole", yetAnotherAnotherConnectionRoleId);
service.Update(connection);
I wrote this simple query:
var connectionString = String.Format("Url={0}; Username={1}; Password={2}; Domain={3}", url, username, password, domain);
var myConnection = CrmConnection.Parse(connectionString);
CrmOrganizationServiceContext _service = new CrmOrganizationServiceContext(myConnection);
var whoAmI = _service.Execute(new WhoAmIRequest());
var query = new QueryExpression
{
EntityName = "phonecall",
ColumnSet = new ColumnSet(true)
};
query.PageInfo = new PagingInfo
{
Count = 20,
PageNumber = 1,
PagingCookie = null
};
query.Orders.Add(new OrderExpression
{
AttributeName = "actualstart",
OrderType = OrderType.Descending
});
query.Criteria = new FilterExpression() { FilterOperator = LogicalOperator.And };
query.Criteria.AddCondition("call_caller", ConditionOperator.In, lines);
var entities = _service.RetrieveMultiple(query).Entities;
I have a program which runs this query every minute. On the first execution the correct results are displayed but for subsequent queries the results never change as I update records in CRM.
If I restart my program the results refresh correctly again on the first load.
Why are the results not updating as records are modified in CRM?
It is the CrmOrganizationServiceContext that is doing the caching - I found the following worked a treat and the results of my RetrieveMultiple are no longer cached :)
Context = new CrmOrganizationServiceContext(CrmConnection.Parse(connectionString));
Context.TryAccessCache(cache => cache.Mode = OrganizationServiceCacheMode.Disabled);
RetrieveMultiple always brings back fresh results so there must be some other aspect of your program which is causing stale data to be displayed.
I am using Visual 2010 with store procedures. I see all examples of EF involve mapping to the DB. Can I call them without mapping? We are creating a ton new procs though out the week...its would be alot of work/coordination to update the mapping though out the development. I was thinking of using Enterprise library instead?
DataSet ds = new DataSet();
string connectionString = (myObjectContext.Connection as System.Data.EntityClient.EntityConnection).StoreConnection.ConnectionString;
using (SqlConnection conn = new SqlConnection(connectionString))
{
SqlCommand cmd = new SqlCommand("EXEC Sp_MyStoredProcedure #param1, #param2", conn);
cmd.Parameters.Add(new SqlParameter("#param1", param1));
cmd.Parameters.Add(new SqlParameter("#param2", param2));
SqlDataAdapter adapter = new SqlDataAdapter(cmd);
adapter.Fill(ds);
return ds;
}
I have an entity called Invoice and an entity called InvoiceItem.
There is a one to many relationship called new_invoice_invoiceitem.
There is a LookupAttribute in InvoiceItem called new_parent_invoice_invoiceitem.
I am trying to retrieve the InvoiceItems that are related to the Invoice with a particular ID using the following code:
QueryExpression query = new QueryExpression();
query.EntityName = "new_invoiceitem";
query.ColumnSet = new AllColumns();
ConditionExpression condition = new ConditionExpression();
condition.AttributeName = "new_parent_invoice_invoiceitem";
condition.Values = new object [] { new Guid("fe1009cc-e034-49d5-bc59-ab4c3091a6f9") };
condition.Operator = ConditionOperator.Equal;
FilterExpression filter = new FilterExpression();
filter.AddCondition(condition);
query.Criteria = filter;
RetrieveMultipleRequest request = new RetrieveMultipleRequest();
request.Query = query;
RetrieveMultipleResponse response = (RetrieveMultipleResponse)crmService.Execute(request);
BusinessEntityCollection bec = response.BusinessEntityCollection;
The code runs without errors but the BusinessEntityCollection is always empty even though there are records in Dynamics.
Any idea what I'm doing wrong?
Thanks,
David
Try setting request.ReturnDynamicEntities = true
